DAG Meets BFT: The Next Generation of BFT Consensus
An overview of recent developments in the theory and practice of directed acyclic graph (DAG) based Byzantine Fault Tolerance (BFT) consensus. Alexander Spiegelman (Aptos) discusses how the Narwhal protocol decouples data from meta to build a highly efficient DAG. Sasha then explains how the protocol can locally (with zero communication overhead) totally order the nodes of the DAG by using DAG-Rider/Tusk/Bullshark.
